"Any place to put a flier up we've done that, now we are just going out further and further because I don't know what else to do," Moss said.

Moss drove all the way from Tacoma to help in the search for Huston.

"Everybody's praying and hoping. We are getting churches involved, anything we can do," Moss said.

Moss grew up with Huston's husband, Kallen, and knows he needs all the support he can get.

"It's overwhelming. I truly appreciate what you are doing. Obviously I am an emotional wreck right now, but it warms my heart to see so many people trying," Kallen Huston said.

While friends continue the search, Kallen is trying to keep things as normal as possible for his two young sons.

"Right now mommy is on vacation," Kallen said.

The Find Jennifer Huston Facebook page now has a reward for her safe return, Kallen told KATU on Monday.

Kallen says his wife has no history of medical or mental health issues that could explain her disappearance.

He says aside from the normal pressures of raising two young boys, everything was fine at home, and just can't imagine his wife leaving her family voluntarily.

"I can honestly and truly tell you even if there was something I wasn't aware about where there was something she wasn't happy with about me, with our relationship, she would never leave our boys. She's been gone three days now. There's no way she would leave," Kallen said.

Jennifer Huston was last seen on surveillance video at a Circle K in Newberg on Thursday. She was driving a 1999 dark green Lexus LX 470 SUV.

"We can confirm that it was Jennifer driving her car away from the Circle K gas station," said Kallen Huston in a text message to KATU. "There didn't appear to be anyone else in the car with her, but as we know, surveillance video can be somewhat grainy."

Searchers used an airplane to look for Huston for nearly three hours Sunday night, Kallen said.
